Computational Fluid Dynamics (CFD) using Smoothed Particle Hydrodynamics (SPH) has a wide range of applications to solve problem in engineering and science. SPH is a mesh-free Lagrangian method and well suited to the simulation of complex and free surface flows. The SPH method was originally used to model astrophysical problems by Lucy [1]} and Gingold and Monaghan [2]}. Three-dimensional SPH method has been studied numerically by Monaghan [3]} in a field of astrophysical fluid dynamics processes.
